Dalvik (software)

Dalvik is a discontinuedprocess virtual machine (VM) in Google's Android operating system that executes applications written for Android. Dalvik is an integral part of the Android software stack in Android versions 4.4 "KitKat" and earlier, which is typically used on mobile devices such as mobile phones and tablet computers, and more recently on devices such as smart TVs and wearables. Dalvik is open-source software, originally written by Dan Bornstein, who named it after the fishing village of Dalvík in Eyjafjörður, Iceland.

Programs for Android are commonly written in Java and compiled to bytecode for the Java virtual machine, which is then translated to Dalvik bytecode and stored in .dex (Dalvik EXecutable) and .odex (Optimized Dalvik EXecutable) files; related terms odex and de-odex are associated with respective bytecode conversions. The compact Dalvik Executable format is designed for systems that are constrained in terms of memory and processor speed.

The successor of Dalvik is Android Runtime (ART), which uses the same bytecode and .dex files (but not .odex files), with the succession aiming at performance improvements transparent to the end users. The new runtime environment was included for the first time in Android 4.4 "KitKat" as a technology preview, and replaced Dalvik entirely in later versions; Android 5.0 "Lollipop" is the first version in which ART is the only included runtime.

DEX (protocol)

DEX (data exchange) is a format for collecting audit and event data from vending machines.

DEX was introduced in the late 1980s by bottlers who provided product to vending machines. It was intended to improve auditing of vending machines, simplify inventory management. DEX records cash in/out, product movement and other audit data. The format was adopted as a standard by the National Automatic Merchandising Association Technology Committee after it was already in use by bottlers. It was included in NAMA VDI version 1.0, announced in 2009.

Network (film)

Network is a 1976 American satirical film written by Paddy Chayefsky and directed by Sidney Lumet, about a fictional television network, UBS, and its struggle with poor ratings. The film stars Faye Dunaway, William Holden, Peter Finch, and Robert Duvall and features Wesley Addy, Ned Beatty, and Beatrice Straight.

The film won four Academy Awards, in the categories of Best Actor (Finch), Best Actress (Dunaway), Best Supporting Actress (Straight), and Best Original Screenplay (Chayefsky).

In 2000, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". In 2002, it was inducted into the Producers Guild of America Hall of Fame as a film that has "set an enduring standard for U.S. American entertainment". In 2006, the two Writers Guilds of America voted Chayefsky's script one of the 10 greatest screenplays in the history of cinema. In 2007, the film was 64th among the 100 greatest American films as chosen by the American Film Institute, a ranking slightly higher than the one AFI had given it ten years earlier.

Network (lobby group)

Network (stylized NETWORK), A National Catholic Social Justice Lobby, is headquartered in Washington, D.C. The organization focuses its lobbying efforts in the areas of economic justice, immigration reform, healthcare, peace making and ecology. Sister Simone Campbell is the executive director of NETWORK.

History

Network was founded in December 1971 when 47 Catholic Sisters involved in education, healthcare, and other direct service activities gathered from across the U.S. at Trinity College in Washington, D.C. , with the intent to form a new type of justice ministry. This was a time when the Catholic Church was undergoing dramatic changes in response to Vatican II reforms and calls from the Vatican and U.S. Bishops to seek "Justice in the World". Individual women religious had already become involved in the civil rights movement, and anti-war activism.

The 47 Sisters voted to form a national "network" of Sisters to lobby for federal policies and legislation that promote economic and social justice. This was the founding of Network, A National Catholic Social Justice Lobby. In April 1972 they opened a two-person office in Washington, D.C.
